LOCK.

Application filed July 3, 1918.

To all whom it may concern:

Be it known that I, HENRY G. Vororrr, of New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

This invention relates to looks, and more particularly to an emergency exit or socalled panic lock of the mortise type.

In applying to doors emergency exit locks of the mortise type provided with a separate escutcheon plate upon which the emergency lever bar or so-called panic bar is pivotally mounted, considerable di'fiiculty has been encountered heretofore in mounting the escutcheon upon the face of the door and retaining the same in proper alignment with the lock which is mortised within the door. Since the emergency lever bar whi1:h is pivotally mounted upon the escutcheon plate cooperates with a sliding element of the mortise lock to retract the latch bolt, it is important, in order that the parts may operate properly, that the escutcheon plate be positioned and maintained in proper alignment with its mortise lock.

The principal object of the present invention is to provide an emergency exit lock and its escutcheon plate upon which an emergency lever bar is pivotally mounted with cooperating means for properly positioning the escutcheon plate relatively to the lock and for retaining this plate in proper alignment with its lock.

Another object of the invention is to pro-. vide an anti-friction roller between the emergency lever bar and the element within the mortise lock which this bar engages and operates.

Still another object of the invention is to improve the construction of the operating elements within the emergency exitlock and to reduce the number of parts within the lock required to perform the desired functions.

To these and other ends, the invention,

consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings,

Fig. 1 is a side elevation of a fragmentary portion of a door having my emergency exit lock applied thereto;

Fig. 2 is an edge view of the portion of Serial No. 243,126.

the door shown in Fig. 1, having my lock applied thereto;

Fig. 3 is a side view of my improved mortise lock removed from the door;

Fig. 1 is a sectional view taken on line 4-4 of Fig. 1, looking in the direction of the arrows;

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 1, looking in the direction of the arrows Fig. 6 is a side view of the lock shown in Fig. 3 with the cap plate removed;

Fig. 7 is a sectional view taken substantially on the line 77 of Fig. 6, looking in the direction of the arrows; and 7 Figs. 8 and 9 are plan views of detail features of my lock.

The drawings may be briefly described as disclosing a fragmentary portion of a door, designated by the numeral 10-, in which door is mounted an emergency exit lock 11 of the mortise type. Upon the inside of the door 10 is mounted an escutcheon plate 12, and upon the outside of the door a second escutcheon plate 13 The inner escutoheon plate 12 is provided with a pair of spaced lugs 14, between which the emergency exit lever 15 is pivotally mounted. The principal object of my invention, as above briefly stated, is to provide cooperat ing means between the mortise lock 11 and the inside esc-utcheon plate 12, which will insure that when the lock and the plate are mounted upon a door, these elements will be properly positioned relative to each other and will be rigidly secured in this position so that the emergency exit lever 15 will have its inner end properly positioned relative to the mortise lock, and so that the escutcheon plate 12 will not be worked loose upon the door by the numerous severe strains to which it may be submitted when heavy pressure is exerted'upon the emergency exit bar or panicbar 16 which operates the lever 15.

The means which I have provided for properly positioning the escutcheon plate 12 relative to the lock 11 consists of a plurality of lugs such as 17 which proferably are formed integrally upon the upper edge of the lock casing and project upwardly therefrom, as shown more particularly in Figs. 3 and 6. These lugs have drill holes 18 formed therethrough. Upon the inner face of the inner escu'tcheon plate 12 are formed a corresponding number of bosses 19 having drill holes formed there through, as shown more particularly in Fig. 5, and upon the inner face of the outer escutcheon' plate 13 are formed similar bosses 19 having threaded sockets therein. These escutcheon plates are adapted to be rigidly secured to the opposite sides of the door by bolts 20 which extend through the plate 12 and the bosses formed thereupon, through the drill holes formed in the bosses 17 upon the lock 11 and havethreaded engagement with the threaded sockets formed in the bosses 19 upon the outer escutcheon plate, as shown particularly in Fig. 5, the arrangement being such that the workman mounting the look upon the door must get the mortise lock and the escutcheon plates in proper alignment before he will be able to insert the bolts 20 through the drill holes formed in the inner escutcheon plate and the lugs 17, thereby'insuring that whenthe plates and lock are secured in place upon vthe door by the bolts 20, they will be in proper alignment and rigidly secured in this position. The lock and escutcheon plates herein disclosed may be applied either to a hollow metal door or to a solid wooden door. I have illustrated my look as applied to a hollow metal door having the metal walls 10 and 10". When my lock isapplied to this type of door. the bosses 19 and 19 should be of sufiicient length to contact with the lugs 17 upon the lock 11 when the escutcheon plates 12 and 13 are held in their proper engagement with the faces of the door upon which they are mounted, so that when the parts are assembled, the lock 11 will be held by the ends of the bosses from moving transversely within the hollow metal door, shown particularly in Figs. 4 and 5. It is not necessary to-provide lugs upon the lower face of my lock 11, similar to the lugs 17, asthe lugs upon the upper edge of the lock will be sufficient to properly position the escutcheon plates, and, furthermore, such lugs formed upon the lower face of the lock would, in some cases, be in the way of the proper operation of the finger which is formed upon the emergency lever bar 15. I therefore provide upon the lower portion of the escutcheon plates 12 and 13, bosses 19 and 19 similar to those 55 formed upon the upper portions of these plates. The plate 12 and the bosses 19 have drillholes formed therethrough adapted to receive the bolts 20 which extend through this plate and have threaded engagement withthe sockets formed in the bosses 19.

The lock 11 consists preferably of the usualtype of hollow casing provided with a"face i plate 2 1,upon which is pivotally mounted in a well known manner a latch bolt 22and a dogcontrolling plunger 23.

i The latch bolt isprovided with a latch bolt stem 24 for operating the same. The outer end of this stem, which is not shown, is pivotally secured to the latch bolt 22, and the rear end is provided with a cross-head 25, by means of which the bolt may be retracted. This stem is mounted to slide between a pair of spaced stumps 26, which are rigidly secured to the lock casing, and the latch bolt is normally retained in its protracted position by a coiled spring 27 which reacts against the stumps 26. The dog-controlling plunger 23 is provided with a bolt stem 28 and with a cross-head 29. The dogcontrolling plunger is normally held in its protracted position by a coiled spring 30. The. latch bolt 22 and the dog-controlling plunger 23 may be retained in their retracted position by a key-operated sliding bar 31, the forward end of which is pro vided with a slot 32, which slidably receives a post 33 rigidly secured to the lock casing. The slot 32 and post 33 cooperate to guide the forward end of the sliding bar so that it will move in a longitudinal path when operated by its key. The rear portion of the sliding bar 31 is provided with the usual talons 34 and with a stump 35 mounted. upon a lateral face of this slide. The sliding bar 31 is provided with the usual type of tumblers 36, which are pivotally mounted upon the post 33 and cooperate with the stump 35 upon the sliding bar to retain this bar in either its protracted or retracted position, in a well-known manner. The sliding bar 31 is provided with a downwardly projecting, relatively long finger 37, one face of which rests upon and has sliding engagement with a lug 38 formed upon the lock casing. The sliding bar 31 is provided with a second downwardly directed finger 39, having a notch or seat 40 therein. as shown more particularly in Fig. This seat is adapted to slidably receive the stem 28 which operates the dog-controlling plunger 23 and also serves to retract this plunger by contacting with the crosshead 29 when the sliding bar 31 is retracted. The spring 30. which normally r etains the plunger 23 in its protracted position, reacts against one face of this finger 39.

The latch bolt 22 is normally dogged in its protracted position by a dogging lever 41 which is pivotally mounted upon a post 42 rigidly secured to the lock casing. This dogging lever is normally urged to its latchdogging position by a spring 43 which reacts against a post 44. The dogging lever 41 is provided with a projecting arm 45, the outer end of which is retained in contact with one faceof the cross-head 29 by the spring 43, the arrangement being such that when the dog-controlling plunger 23 is in its protracted position, the cross-head 29, through the arm 45, swings the lever 41 about its pivot so that the projecting end 46 of th s le e il clear the la ehpbq -22 and permit the same to beiretraeted, but when the dog-controlling plunger :is moved to its retracted position by contacting with the strike plate upon the door jamb, when the door is closed, the stem-28 and the cross-head 29 upon the inner end of this stem will be moved inwardly and thereby permit the dogging lever 41 to be swung about its-pivot 42 so that the end 46 will lie behind the latch bolt and prevent the same from being eretracted.

The lock casing has a notch out v1n its lower edge, through which projects the emergency slideor lifter 47. The lower end of this slide has a substantially U-shaped configuration, asshown more clearly in Fig. 8, and in the clearancespace formed between the opposite legs of the U-shaped construction, is mounted an anti friction roller 49 upon an axle 50. This emergency slide or lifter 47 is constructed so that it will :shde in a vertical direction and is retained in proper path by the opposite faces of this slide, which contact with the walls 4 9 and 50 of the slot formed in the lock cas ng, and the upper portion v48 of the slide is retained in'its proper path by a plural ty of lugs such as 551 and 52. Pivotallymounted upon a stud .53 carried by-the loclrcasmg 1s a swinging lever 54, which is provided with the proj'etions or contact portions '55, 56 and 57. The contact portion 55 of this lever rests against an inner face of the emergency vslide 47, the arrangement being such that the lever 54 is swung about its pivotal mounting 53 when the slide 47 is raised; The projection 56 upon this lever is constructed to cooperate with a projecting portion 558 formed upon the dogging lever 41, and the projecting arm 57 s so constructed that a portion of this arm contacts with one face of the crosshead 25 mounted upon the inner end 9f th latch bolt stem 24, and another portion of this m :57 is po it o d t con ac with a g 59 formed upon the outer end of the firiger 37.

The emergency lever bar 15, which is pivotally mounted between the lugs 1-;4by meansof a pivot pin 60, is provided with an inwardly directed :finger 61 which is positioned to contact with the anti-friction roller 49 and to force the emergency slide 47 into its lock casing when the emergency lever 15 is depressed by exerting pressure on the panic bar 16.

The operation of my device is as follows: The latch bolt 22 and the dog-controlled plunger 23 are normally-held in their protracted position by the springs 27 and 30, but, if desired, both the latch bolt {and the plunger may be simultaneouslyretractediby inserting a key in the key-hole :62 andreracting the slidi g bar :81, whereupfl t ng 3. i l h the s em 28 is l d i y mounted, contacts with the cro ss-head 29 and retracts the dog-controlling plunger. At the sametime. the long projecting finger 37 which is formed integral upon the sliding bar, contacts with the finger-like portion 57 of the lever 54 and swings this lever about its pivot in a rearward direction, but, due to the fact that a portion of this finger 57 contacts with the cross-head 25, when the sliding bar 31 is retracted, the latch bolt 22 will be retracted through the latch bolt stem and the cross-head. It should be noted that whenever the lever 54 is swung about its pivot 53 in a rearward direction, either by means of the finger 37 which contacts with the extension 57 or by means of the emergency slide 47, theinner face of which contacts with the lug 55 formed upon the lever 54, the extension 56 will contact with the projection 58 upon the dogging lever 41 so that this dogging lever-will be swung to its inoperative position, as shown in Fig. 6, in order that the latch bolt 22 may be retracted.

From the above description, it is thought it will be apparent that my emergency lock isso constructed that it may at all times be released by its panic bar from the inside of the door, in order to open the same. When the sliding bar 31 is protracted by a key, not shown, inserted from either side of the door both the latch bolt and the dog-controlling plunger will be released and moved to their protracted position by their operating springs, as shown in Fig. 6. When in this position it will be apparent that the door may be readily opened from the inside of the same by 'means of the panic bar 16, due to the finger 61 formed upon this bar which contacts with the anti-friction roller 49 to raise the slide 47, whereupon the lever 54 is operated to simultaneously swing the dogging lever 41 to its inoperative position and :to retract the latch bolt 22. The dogcont-rolling plunger 23 does not need to be operated in order to permit the door to be opened, since this plunger does not enter an opening in the strike plate upon the door ja1nb,but is forced into its lock'by the strike plate,-in order that the dogging lever 41 will be permitted to swing to its dogging position as soon as the door reaches its closed position. When the slide bar 31 is operated by its key to retract the latch bolt and the dog-controlling plunger, the door is unlocked and may beopened from either the inside or outside of the same.

It will be obviousthat my novel means for mounting the escutcheon plates upon thedoor in proper alignment with a mortise lock is not limited to the particular means herein disclosed for securing the escutcheon 12 to the lock 11, since numerous changes may be made in the device herein disclosed ating lever is without departing from the scope of my invention; nor is m invention limited to the particular type of panic bar herein disclosed, since any desired type of panic bar or emergency lever may be used without departing from the scope of my invention as defined in the annexed claims. Further more, although I have disclosed an antifriction roller mounted upon the emergency slide 47, it will be apparent that this roller, in order to reduce the friction between the slide 4:7 and the finger 61, may be mounted upon either the emergency slide or the finger, and it will be'apparent that any form of anti-friction device may be substituted for the roller herein disclosed without departing from the scope of my invention as defined in the claims.
